is there any option how can I specify custom hostname for docker container instead of default generated one? Running locally I am able to do this using -h option:
docker run -h custom_host_name image
There is no current functionality to configure the hostname of the Docker container in the Docker run command.
Feel free to open a feature request here: https://bitbucket.org/site/master/issues
Out of curiosity, what's your use-case here?
thanks for info. I got some pre-configured docker image with services bound to a specific host (dbserver). As content of /etc/hosts file is managed by a docker itself, any changes to /etc/hosts during docker build (such as adding a specific host) will be overwritten in the runtime. So the best option is to provide host during container creation with -h dbserver option. Otherwise services will fail due to unresolvable host.
Because I was not able to configure that in such a way in bitbucket I have created my own docker image (based on the original) with custom entrypoint startup script that adds proper host record into /etc/hosts.
#!/bin/bash if [ `hostname` != "dbserver" ] then echo "127.0.0.1 dbserver" >> /etc/hosts fi
